FIELD OF THE INVENTION

This invention relates to truck cab brake lights, and in particular to systems, devices, and methods for replacing an existing truck cab braking light with an after-market or retrofit universal elongated light emitting diode (LED) light device which can easily replace existing truck cab rear facing brake lights, and do not require different types of light devices for different trucks, and can be rigidly sealed and seated against the rear of the truck cab with additional fasteners.

BACKGROUND AND PRIOR ART

Trucks are often used on construction sites to deliver and retrieve supplies and materials, and when stopped often turn off their front and rear lights and brake lights on the rear of their trucks as well as the rear facing brake lights on the upper rear of the truck cabs. A problem occurs that the trucks are not easily visible when stopped when their lights are turned off during these stops. As such, it can be dangerous to others when these trucks are stopped since their visibility can be severely limited, especially in dark locations or during storms, and the like.

Leaving on the truck vehicle's lights on may not be enough to bring attention to the stopped trucks. As such, there is a need to have extra lights for bringing attention to a stopped truck vehicle to increase the visibility of the stopped vehicle as well as for safety reasons.

Additionally, standard vehicle lights are usually limited to be used for breaking, signaling or similar functions, and are not versatile to bring separate attention to a stopped truck vehicle.

Over the years various types of products have been proposed for providing extra lights to truck cab brake lights, but would not be satisfactory as an after-market product. U.S. Pat. No. 8,956,020 to Graves et al. describes an auxiliary lamp mounting adapter assembly for vehicles that include truck cabs. This adapter assembly requires the rear brake light on the rear of the truck cab be removed and the opening in the back of the cab for the existing light being exposed. A new housing having a main opening that generally matches and aligns with the existing opening in the back of the truck cab. The new housing includes auxiliary lights to the right and/or left of the main opening. The removed brake light can be remounted through the main opening in the new housing, and fastened to the cab, without having to use additional fasteners, that can penetrate into the rear cab.

A problem with this adapter assembly is that by using the existing rear brake light with this adapter assembly, the resulting light could appear to be an obvious modification to the existing brake light and not look like original truck equipment.

Another problem is that many different types of adapter assemblies would need to be manufactured for the different U.S. and foreign tucks, since truck cabs do not have identical brake lights on the back of their cabs.

Additionally, the auxiliary lights would require separate wiring that must connect to the existing wiring, and could cause problems if not properly connected.

Still furthermore, by only using the existing brake light fasteners, the longer replacement housing may not be properly sealed and seated against the truck cab, and could vibrate and separate during regular use. The larger replace housings could also cause the existing fasteners loose causing water leaks into the cab.

Thus, the need exists for solutions to the above problems with the prior art.

Referring to FIGS. 1-14, fasteners 60, such as but not limited to flat headed screws, and the like, can pass through the holes 48, 28 and 18, and allow for the replacement light system 1 to attach directly to the upper exterior rear portion of the truck cab. While some existing fastener openings used for attaching the factory brake light to the upper rear portion of the truck cab, the invention allows for drilling additional holes into the metal to both sides of the existing openings in the upper exterior rear portion of the tuck cab. Between approximately four to approximately six or more additional holes 80 can be drilled into the upper rear exterior portion of the truck cab and allow for a more secure and uniform attachment of all of the replacement light system to the upper exterior rear portion of the truck cab. An identical number of holes 80 can be drilled on both sides of the existing openings 115 that exist. In a preferred embodiment six additional holes 80 are drilled into the upper exterior rear portion of the truck cab, with three new holes to the left side and three new holes to the right side of the existing openings 115. To seal the replacement light system 1, an elastomeric type weather strip 50 can be used and be sandwiched between a rear face of the support member 20 and the upper exterior rear portion of the truck cab.

The novel replacement light system 1 can function by having the LEDs (light emitting diodes) flash on and off, go into continuous light emissions, and use different colors, such as but not limited to red to show braking, and white for safety, and other colors and the like. The LEDS (light emitting diodes) in the left printed circuit board 30A can be separately controlled from the LEDS (light emitting diodes) 30B in the center printed circuit board 30B, and from the LEDS (light emitting diodes) 30C in the right printed circuit board 30C. Each of the three sections of LEDs in 30A, 30B, 30C can operate independently from one another, and also in uniform with one another, or other combinations with one another.

A preferred embodiment of operating the different sections of LEDS 30A, 30B and 30C will now be described.

1. When breaks are applied in the truck the center light section of LEDS 30B can emit red color.

2. When the truck is put in reverse the center LED's 30B can light up white & then red as the truck brakes are applied.

3. When a bed light switch is activated all LED's 30A, 30B and 30C comes on white.

4. When safety lights are activated (switch in cab) all LED's 30A, 30B and 30C can be activated and go into pre-programmed patters (strobe, flash, chase, and the like)

5. If safety light is active during travel and the truck brakes are applied the center section 30B will switch to red so that the 3rd brake light function is still retained.

Other operations can allow for the left LEDS 30A and right LEDS 30C to be turn on respectively, when left and right vehicle turn signals are used and the like.

While the embodiments are primary described for use with trucks 100, the replacement light system 1 can also be used in other application, such as but not limited to be used with automobiles, watercraft, and the like.

The term “approximately” is similar to he term “about” and can be +/−10% of the amount referenced. Additionally, preferred amounts and ranges can include the amounts and ranges referenced without the prefix of being approximately.
